But one thing it's not packed with is a fingerprint sensor. Like many phones in 2017, the iPhone X goes for a nearly all-screen design, which means there's no more room for a front Touch ID sensor. Rather than locate a fingerprint sensor on the back, like many phones have done, Apple chose to do away with Touch ID entirely. Instead, the X is relying only on the new "Face ID" facial recognition feature for biometric security.
